Note 1. Basis of Presentation – Going Concern Uncertainties ProtoKinetix, Incorporated (the “Company”), a development stage company, was incorporated under the laws of the State of Nevada on December 23, 1999. The Company is a medical research company whose mission is the advancement of human health care. The Company is currently researching the benefits and feasibility of synthesized Antifreeze Glycoproteins (“AFGP”) or anti-aging glycoproteins, trademarked AAGP. During the year ended December 31, 2015, the Company acquired certain patents and rights for cash consideration of $30,000 (25,000 Euros), as well as additional patent applications for cash consideration of $10,000 and 6,000,000 share purchase warrants with a fair value of $25,000 (Note 4). The Company’s financial statements are prepared consistent with accounting principles generally accepted in the United States applicable to a going concern. The Company has not developed a commercially viable product, has not generated any significant revenue to date, and has incurred losses since inception, resulting in a net accumulated deficit at March 31, 2026. These factors raise substantial doubt about the Company’s ability to continue as a going concern. The Company needs additional working capital to continue its medical research or to be successful in any future business activities and continue to pay its liabilities. Therefore, continuation of the Company as a going concern is dependent upon obtaining the additional working capital necessary to accomplish its objective. Management is presently engaged in seeking additional working capital through equity financing or related party loans. In addition, any significant disruption of global financial markets, reducing our ability to access capital, could negatively affect our liquidity and ability to continue operations. The exact impact is and will remain unknown and largely dependent upon future developments, including but not limited to restrictions on the activities of our domestic and international suppliers and shipment of goods. The accompanying financial statements do not include any adjustments to the recorded assets or liabilities that might be necessary should the Company fail in any of the above objectives and is unable to operate for the coming year.

Note 2. Summary of Significant Accounting Policies Basis of Presentation The accompanying unaudited financial statements have been prepared by the Company in conformity with accounting principles generally accepted in the United States of America (“US GAAP”) applicable to interim financial information and with the rules and regulations of the United States Securities and Exchange Commission. Accordingly, certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles have been condensed, or omitted, pursuant to such rules and regulations. In the opinion of management, the unaudited interim financial statements include all adjustments necessary for the fair presentation of the results of the interim periods presented. All adjustments are of a normal recurring nature, except as otherwise noted below. These financial statements should be read in conjunction with the Company’s audited financial statements and notes thereto for the year ended December 31, 2025, included in the Company’s Annual Report on Form 10-K, filed September 3, 2026, with the Securities and Exchange Commission. The results of operations for the interim periods are not necessarily indicative of the results of operations for any other interim period or for a full fiscal year. Use of Estimates Preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. The more significant accounting estimates inherent in the preparation of the Company’s financial statements include estimates as to valuation of equity related instruments issued, deferred income taxes, and the useful life and impairment of intangible assets. Cash Cash consists of funds held in checking accounts. Cash balances may exceed federally insured limits from time to time. Fair Value of Financial Instruments Financial instruments, which includes cash, accounts payable and accrued liabilities are carried at amortized cost, which management believes approximates fair value due to the short-term nature of these instruments. The Company measures the fair value of financial assets and liabilities pursuant to ASC 820 "Fair Value Measurements and Disclosures" which defines fair value, establishes a framework for measuring fair value, and expands disclosures about fair value measurements. ASC 820 establishes a fair value hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The policy describes three levels of inputs that may be used to measure fair value: Level 1 – quoted prices in active markets for identical assets or liabilities. Level 2 – quoted prices for similar assets and liabilities in active markets or inputs that are observable. Level 3 – inputs that are unobservable (for example cash flow modeling inputs based on assumptions). At March 31, 2026, there were no other assets or liabilities subject to additional disclosure. Income Taxes The Company accounts for income taxes following the assets and liability method in accordance with the ASC 740 "Income Taxes." Under such method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. The Company applies the accounting guidance issued to address the accounting for uncertain tax positions. This guidance clarifies the accounting for income taxes, by prescribing a minimum recognition threshold a tax position is required to meet before being recognized in the financial statements as well as provides guidance on derecognition, measurement, classification, interest and penalties, accounting in interim periods, disclosure and transition. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years that the asset is expected to be recovered or the liability settled. Intangible assets – patent and patent application costs The Company owns intangible assets consisting of certain patents and patent applications. Intangible assets acquired separately are measured on initial recognition at cost. Following initial recognition, intangible assets are carried at cost less any accumulated amortization and any accumulated impairment losses. Subsequent expenditures are capitalized only when they increase the future economic benefits embodied in the specific asset to which they relate. All other expenditures are recognized in profit or loss as incurred. As at March 31, 2026, the Company does not hold any intangible assets with indefinite lives. Intangible assets with finite lives are amortized over the useful economic life and assessed for impairment whenever there is an indication that the intangible asset may be impaired. The amortization method and amortization period of an intangible asset with a finite life is reviewed at least annually. Changes in the expected useful life or the expected pattern of consumption of future economic benefits embodied in the asset is accounted for by changing the amortization period or method, as appropriate, and are treated as changes in accounting estimates. Amortization is recognized in profit or loss on a straight-line basis over the estimated useful lives of the Company's patents, whereas no amortization has been recognized on the not yet approved patent application costs at March 31, 2026. Research and Development Costs Research and development costs are expensed as incurred. This includes all research consultant’s fees and costs of contract research organizations. Loss per Share and Potentially Dilutive Securities Basic loss per share is computed by dividing the net loss available to common stockholders by the weighted average number of common shares outstanding in the period. Diluted loss per share takes into consideration common shares outstanding (computed under basic earnings per share) and potentially dilutive securities.

Share-Based Compensation The Company has granted warrants and options to purchase shares of the Company’s common stock to various parties for consulting services. The fair values of the warrants and options issued have been estimated using the Black-Scholes Option Pricing Model. The Company accounts for stock compensation with persons classified as employees for accounting purposes in accordance with ASC 718 “Compensation – Stock Compensation”, which recognizes awards at fair value on the date of grant and recognition of compensation over the service period for awards expected to vest. Cliff Vesting is used and awards vest on the last day of the vesting period. The fair value of stock options is determined using the Black-Scholes Option Pricing Model. The fair value of common shares issued for services is determined based on the Company’s stock price on the date of issuance. Share-based compensation for non-employees in exchange for goods and services used or consumed in an entity’s own operations are also recorded at fair value on the measurement date and accounted for in accordance with ASC 718. The measurement of share-based compensation is subject to periodic adjustment as the underlying instruments vest. The fair value of stock options is estimated using the Black-Scholes Option Pricing Model and the compensation charges are amortized over the vesting period. Common stock Common stock issued for non-monetary consideration are recorded at their fair value on the measurement date and classified as equity. The measurement date is defined as the earliest of the date at which the commitment for performance by the counterparty to earn the common shares is reached or the date at which the counterparty’s performance is complete. Transaction costs directly attributable to the issuance of common stock, units and stock options are recognized as a deduction from equity, net of any tax effects. Related Party Transactions A related party is generally defined as (i) any person that holds 10% or more of the Company’s securities and their immediate families, (ii) the Company’s management, (iii) someone that directly or indirectly controls, is controlled by or is under common control with the Company, or (iv) anyone who can significantly influence the financial and operating decisions of the Company. A transaction is considered to be a related party transaction when there is a transfer of resources or obligations between related parties. Recent Accounting Pronouncements Certain new accounting pronouncements that have been issued are not expected to have a material effect on the Company’s financial statements.

Share-Based Compensation The Company has granted warrants and options to purchase shares of the Company’s common stock to various parties for consulting services. The fair values of the warrants and options issued have been estimated using the Black-Scholes Option Pricing Model. The Company accounts for stock compensation with persons classified as employees for accounting purposes in accordance with ASC 718 “Compensation – Stock Compensation”, which recognizes awards at fair value on the date of grant and recognition of compensation over the service period for awards expected to vest. Cliff Vesting is used and awards vest on the last day of the vesting period. The fair value of stock options is determined using the Black-Scholes Option Pricing Model. The fair value of common shares issued for services is determined based on the Company’s stock price on the date of issuance. Share-based compensation for non-employees in exchange for goods and services used or consumed in an entity’s own operations are also recorded at fair value on the measurement date and accounted for in accordance with ASC 718. The measurement of share-based compensation is subject to periodic adjustment as the underlying instruments vest. The fair value of stock options is estimated using the Black-Scholes Option Pricing Model and the compensation charges are amortized over the vesting period.

Common stock Common stock issued for non-monetary consideration are recorded at their fair value on the measurement date and classified as equity. The measurement date is defined as the earliest of the date at which the commitment for performance by the counterparty to earn the common shares is reached or the date at which the counterparty’s performance is complete. Transaction costs directly attributable to the issuance of common stock, units and stock options are recognized as a deduction from equity, net of any tax effects.

Related Party Transactions A related party is generally defined as (i) any person that holds 10% or more of the Company’s securities and their immediate families, (ii) the Company’s management, (iii) someone that directly or indirectly controls, is controlled by or is under common control with the Company, or (iv) anyone who can significantly influence the financial and operating decisions of the Company. A transaction is considered to be a related party transaction when there is a transfer of resources or obligations between related parties.

Recent Accounting Pronouncements Certain new accounting pronouncements that have been issued are not expected to have a material effect on the Company’s financial statements.
